Question

Which of the following organic compounds has same hybridisation as it's combustion product-(CO2) ? 1 ethane 2 ethyne 3ethene 4ethanol

Answer 1

Ethene.. Ethene and CO2 are Sp2 hybridized

Answer 2

Answer:

The ethyne and carbon dioxide molecules possess sp hybridisation.

Explanation:

• The carbon dioxide molecule has its carbon atom in sp hybridised state.
• Ethyne molecule also has the carbon atom in the sp hybridised state. Each of the sp hybrid orbitals is associated with 50% s and p character.
• During the production of alkanes(CH₄), sp³ hybridisation occurs.
• In the ethene molecule, the sp² hybrid orbitals of one carbon atom axially overlap with the sp² hybridised orbital of another carbon atom.
• In ethanol, C is sp³ hybridised.

Thus, ethyne and carbon dioxide molecules have their carbon atom in sp hybridised state.
